Overview
The FOD3120SDV is a 2.5 A output current gate drive optocoupler produced by ON Semiconductor. It is designed to drive most medium power IGBTs and MOSFETs, particularly suited for fast switching driving in motor control inverter applications and high-performance power systems. The device utilizes ON Semiconductor’s proprietary coplanar packaging technology, Optoplanar®, and an optimized IC design to achieve high noise immunity characterized by high common mode rejection. It consists of a gallium aluminum arsenide (AlGaAs) light emitting diode optically coupled to an integrated circuit with a high-speed driver for a push-pull MOSFET output stage.
